In the last decade, aircraft-induced environmental issues have attracted much research interest. In addition to studies on performance related emissions, air pollution and emissions in the field of airports also draw attention. Within this framework, the Antalya International Airport, one of the busiest airports in Turkey, is assessed from the viewpoint of the environment and economics. The present paper reveals the environmental impact and environmental cost of emitted exhaust gases from aircraft operating at the Antalya International Airport in July, 2018, the busiest period in the year. Within this scope the emissions indexes of each exhaust gas, global warming potential and environmental cost of various aircraft types and airways are calculated. To determine these parameters, real-time measurement data has been obtained from the Ministry of Transport and Infrastructure of the Republic of Turkey. At the end of the analyses, aircraft of the B737 family are found to have the highest global warming potential and environmental cost, with values of 630,633.3 GWP and 39,723.4 Euros, respectively. In a future study, the authors intend to evaluate particulate matter emissions at the same airport.
